Nanny in english

I'm an 18 years old girl, who would like to look after children from the morning 'till afternoon. Working hours are between 9-10 am. till 5-6 pm.
I am a very reliable, honest and responsible girl, who was teaching english during summer for kids. I finished a british private high school where I did the Cambridge system.  I'm interested in someone who has a child that wants to learn english. I can play, teach, sing and look after her/him ONLY in English.
